ICU: Miniature NLU programs from Schank and Riesbeck

This directory contains Common Lisp versions of the miniature
natural language understanding programs from
Roger C. Schank and Christopher K. Riesbeck, "Inside Computer
Understanding" Lawrence Erlbaum Associates, 1981.
The distribution includes the SAM, ELI, and Tale-Spin miniatures. It
will eventually include copies of the miniature versions of PAM, and
POLITICS.
Also included in the distribution are:
- FOR Macro. This is the generalized iteration macro found, among
other places, in Charniak's "Artificial Intelligence Programming"
(1987). An older version of it is used in the original
versions of the mini programs.
- CD Functions. This is a set of functions for manipulating and
matching lisp representations of Conceptual Dependency formulas.
